Abstract: In order to analyze the effect of atomization cooling in the partial high-temperature mining face，a describing technique of two-phase flow called Eulerian-Lagrangian method is adopted to simulate the effect of atomization cooling，and the coupling of droplet and wet air is taken into account in the process of calculation.The results of the numerical calculation show that the temperature of flow declines 4 ℃ rapidly after once atomization cooling，which satisfies the demand of cooling in mine.And the effective distance of every row of atomizers is 10 m in the direction of caving face.The temperature of flow goes up 1.5 ℃ after cooling.As a whole，the temperature of flow in caving face goes up statutorily.The cooling effect changes with flux of atomizer as a format of minus exponent.The effect of atomization cooling is obvious in the range of 70°~90° for the spraying angle，and a high pressure mist atomizer can improve the effect of atomization cooling distinctly.
